//! [DataFusion](https://github.com/apache/datafusion)
//! is an extensible query execution framework that uses
//! [Apache Arrow](https://arrow.apache.org) as its in-memory format.
//!
//! This crate is a submodule of DataFusion that provides types representing
//! logical query plans ([LogicalPlan]) and logical expressions ([Expr]) as well as utilities for
//! working with these types.
//!
//! The [expr_fn] module contains functions for creating expressions.
